3. The abnormal pulse monitor according to any one of claims 1 and 2, by further comprising notifying means of notifying a device user of a judgment result from the abnormality judging means.

4. The abnormal pulse monitor according to any one of claim 1, wherein the abnormality judging means judges abnormality when the pulse calculated by the pulse calculating means is larger than a first pulse threshold value predetermined according to the posture information judged by the posture judging means.

5. The abnormal pulse monitor according to any one of claim 1, wherein, the abnormality judging means judges abnormality when the pulse calculated by the pulse calculating means is smaller than a second pulse threshold value predetermined according to the posture information obtained by the posture judging means.

6. The abnormal pulse monitor according to claim 3, wherein the abnormality judging means judges abnormality when the pulse calculated by the pulse calculating means is larger than a fifth pulse threshold value predetermined according to a combination of the posture information obtained by the posture judging means and the activity amount obtained by the activity amount judging means.

7. The abnormal pulse monitor according to claim 3, wherein the abnormality judging means judges abnormality when the pulse calculated by the pulse calculating means is smaller than a sixth pulse threshold value predetermined according to a combination of the posture information obtained by the posture judging means and the activity amount obtained by the activity amount judging means.

8. The abnormal pulse monitor according to claim 3, wherein the monitor further comprises information storage means of temporarily storing the judgment result, and the abnormality judging means judges the pulse to be abnormal based on a time series variation of the judgment result stored in the information storage means.

9. The abnormal pulse monitor according to any one of claim 1, wherein the monitor further comprises information storage means of temporarily storing the judgment result, and the abnormality judging means judges the pulse to be abnormal based on a frequency in a specified time of the judgment result stored in the information storage means.

10. The abnormal pulse monitor according to any one of claims 1 or 2, further comprising abnormality transmitting means of transmitting abnormality judgment information when the abnormality judging means judges abnormality.

11. An abnormal pulse alarming system, comprising the abnormal pulse monitor of claim 10, and

abnormality receiving means of communicating with the abnormality receiving means and receiving the abnormality judgment information.

12. The abnormal pulse alarming system according to claim 11, further comprising the information indicating means which is connected to the abnormality receiving means and indicates the abnormality judgment information.

13. The abnormal pulse alarming system according to claim 11, further comprising alarming means which is connected to the abnormality receiving means and issues an alarm to a user when the abnormality receiving means receives the abnormality judgment information.

14. The abnormal pulse alarming system according to claim 11, wherein the abnormality transmitting means and the abnormality receiving means further comprise encrypting means of encrypting the abnormality judgment information.

15. The abnormal pulse alarming system according to claim 11, wherein the abnormality receiving means further comprises information indicating/selecting means of indicating information on the information indicating means which is specified beforehand based on the abnormal pulse monitor having transmitted the abnormality judgment information.

16. The abnormal pulse alarming system according to claim 11, wherein the abnormality receiving means further comprises alarm issuing/selecting means of issuing an alarm to the alarming means which is specified beforehand based on the abnormal pulse monitor having transmitted the abnormality judgment information.

17. The abnormal pulse alarming system according to claim 11, wherein the system further comprises abnormality information accumulating means which connects the abnormality receiving means and the information indicating means and accumulates the abnormality information, and a user makes an access to the abnormality information accumulating means at any given time to obtain abnormality information, so that the information indicating means indicates the abnormality information.
