Abstract

A portable electronic apparatus is provided with a plurality of infrared element connectors on the housing surfaces thereof. A detachable infrared emitting/receiving element is electrically connected to one selected from the infrared element connectors which is directed toward the opposite apparatus so as to provide the desired infrared connection. This causes the infrared transmission to be made without changing the direction of the apparatuses.

Claims

1. A portable electronic apparatus having an infrared communication function, the apparatus comprising:

a housing containing electronic circuits including a circuit necessary for the infrared communication function;

a plurality of first connectors provided on outside surfaces of the housing, the first connectors being electrically connected to the circuit contained in the housing; and

a detachable infrared element for emitting and receiving infrared rays, the detachable infrared element including a second connector which is detachably connected to any selected one of the first connectors to provide electrical connection to the circuit contained in the housing and to provided infrared communication from the outside surface of the housing having the selected first connector, and thereby the apparatus is capable of infrared communication in different directions relative to the outside surface of the housing having first connectors.

2. The apparatus according to claim 1, wherein the first connectors are provided in side surfaces of the housing, respectively.

3. The apparatus according to claim 1, wherein the housing has a box-like shape.

4. The apparatus according to claim 3, wherein the first connectors are provided in side surfaces of the housing, respectively.

5. The apparatus according to claim 1, wherein the detachable infrared element further comprises:

an infrared light-emitting device for emitting an infrared ray according to a transmitting signal received from the circuit; and

an infrared detector for detecting an infrared ray and converting the infrared ray into a received signal.

6. The apparatus according to claim 5, wherein the circuit necessary for the infrared communication function comprises:

a transmitter-receiver for transmitting the transmitting signal to the first connectors and receiving the received signal from the one selected from the first connectors;

a user interface for presenting information to a user and inputting instructions and data from the user; and

a controller for controlling the transmitter-receiver and the user interface so as to perform the infrared communication function.

7. The apparatus according to claim 1, wherein each of the first connectors is formed in a recess shape into which the second connector is detachably inserted.

8. The apparatus according to claim 7, wherein each of the first connectors has predetermined number of pins placed in the recess and the second connector has the predetermined number of pin holes into which the pins are inserted when the second connector is inserted into the one selected from the first connectors.

9. The apparatus according to claim 1, wherein each of the first connectors is a port for providing electrical connection to the second connector.

10. An infrared communication method between a portable electronic apparatus and an electronic apparatus which are both provided with an infrared communication capability, the method comprising the steps of:

preparing a plurality of infrared element connectors on different outside surfaces of the portable electronic apparatus;

inserting an infrared emitting-receiving element into an infrared element connector selected from the infrared element connectors to electrically connect the infrared emitting-receiving element with the portable electronic apparatus and to direct the infrared emitting-receiving element in a direction toward the electronic apparatus; and

performing infrared communication with the electronic apparatus through the infrared emitting-receiving element connected to the selected infrared element connector.
