Abstract

The data reception apparatus includes a main processing unit that waits in a standby state so as to be able to receive the connection signal that is transmitted in a first communication mode, and further receives, after reception of the connection signal, the data signal that is transmitted in a second communication mode that is different from the first communication mode; a sub processing unit that is provided in addition to the main processing unit, the sub processing unit being capable of receiving the data signal that is transmitted in the second communication mode; a notification unit that is capable of notifying information to a user; and a notification control unit that controls the notification unit so that the notification unit notifies a communication error to the user if the sub processing unit has received the data signal although the main processing unit has not received the connection signal.

Claims

1. A data reception apparatus that is capable of receiving a connection signal and a data signal sent subsequent to the connection signal both of which are transmitted from a communication partner in one-way communication, the data reception apparatus comprising:

a main processing section that waits in a standby state so as to be able to receive the connection signal that is transmitted in a first communication mode, and further receives, after reception of the connection signal, the data signal that is transmitted in a second communication mode that is different from the first communication mode;

a sub processing section that is provided in addition to the main processing section, the sub processing section being capable of receiving the data signal that is transmitted in the second communication mode;

a notification section that is capable of notifying information to a user; and

a notification control section that controls the notification section so that the notification section notifies a communication error to the user if the sub processing section has received the data signal although the main processing section has not received the connection signal.

2. The data reception apparatus according to claim 1, wherein the sub processing section is capable of detecting a predetermined pattern contained in the data signal, and the notification control section controls the notification section so that the notification section notifies the communication error to the user if the sub processing section has detected the predetermined pattern although the main processing section has not received the connection signal.

3. The data reception apparatus according to claim 2, wherein the predetermined pattern is a pattern that indicates a preamble.

4. The data reception apparatus according to claim 1, wherein the first and second communication modes are communication speeds.

5. The data reception apparatus according to claim 1, further comprising a printing section that performs printing, and a print control section that controls the printing section so that the printing section performs printing on the basis of image data when the main processing section receives the image data as the data signal after reception of the connection signal.

8. The data reception apparatus according to claim 1, wherein the first and second communication modes are synchronization schemes.

9. The data reception apparatus according to claim 1, wherein the first and second communication modes are modulation schemes.

10. The data reception apparatus according to claim 1, wherein said notification section is selected from the group comprising a display section, speaker, and lamp.

6. A data reception method for receiving a connection signal and a data signal sent subsequent to the connection signal both of which are transmitted from a communication partner in one-way communication, the data reception method comprising:

(a) a main processing section waiting in a standby state so as to be able to receive the connection signal that is transmitted in a first communication mode, and further receiving, after reception of the connection signal, the data signal that is transmitted in a second communication mode that is different from the first communication mode;

(b) a sub processing section receiving the data signal that is transmitted in the second communication mode, the step (b) being performed independent of the step (a); and

(c) a notification section notifying a communication error to a user if the data signal has been received in the step (b) although the connection signal has not been received in the step (a).

7. A program that causes the data reception method according to claim 6 to be executed by one or more personal computer.
