【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a sectional view of a charging terminal of the present invention, FIG. 2 is a block diagram of an optical communication device having a built-in charging terminal, and FIG. 3 is a perspective view of an optical communication device having a charging terminal.

First, an outline of an optical communication device having a built-in charging terminal will be described with reference to FIG. 1 is a handy terminal as a device to be charged, 2 is an optical communication device as a charger, 3 is a host computer, 4 is a charging terminal, 5 is an optical communication element, and in the state shown in the figure, the handy terminal 1 is an optical communication device. The figure shows a state in which the device is mounted on the device 2 and charging and communication with the host computer 3 are performed. The handy terminal 1 is a B5 size and can be easily carried, and has a liquid crystal touch panel, an MS-DOS built into a ROM, a large capacity memory, a battery and the like. It can be connected to various input / output devices such as bar code scanners and image scanners, and can be used for commercial or private use. The optical communication device 2 has a remote load function and a charging function capable of communicating with the host computer 3, and is capable of simultaneously charging the battery and communicating at night.

Next, the structure of the charging terminal 4 of the optical communication device 2 will be described with reference to FIG. Here, FIG. 1B is a cross-sectional view taken along the line AA of FIG. 1A, 10 is a bottom surface which is a predetermined surface of the device body, 11 is a terminal rod as a terminal member, 12 is a terminal cover, and 13 is a terminal cover. Is a limit switch, 14 is a power supply control circuit, 15 is a holder, and 16 and 17 are springs. Three terminal rods 11, one for battery, one for ground, and one for power supply, are slidably fitted in the holder 15, and are biased by the spring 16 in the protruding direction from the bottom surface 10 of the device body. The terminal cover 12 is slidably fitted in the hole 20 of the bottom surface 10 and is biased by the spring 17 in the protruding direction from the bottom surface 10. The terminal cover 12 is provided with a hole 21 through which the terminal rod 11 penetrates, and the tip of the terminal rod 11 is substantially flush with the terminal cover 12 so that the terminal rod 11 is mechanically protected. The limit switch 13 is fixed to the extension portion 22 of the holder 15 so that the exit of the terminal cover 12 can be detected. The limit switch 13 supplies electric power to the terminal rod 11 via the power supply control circuit 14, so that the terminal rod 11 is electrically protected.

The operation of such a charging terminal 4 is as follows. When the handy terminal 1 is placed in the recess of the bottom surface 10, the bottom 1a hits the terminal cover 12 and overcomes the biasing force of the spring 17 to cause the terminal cover 12 to move downward. Then, the terminal 1b of the bottom 1a comes into contact with the tip of the terminal rod 11 to be in a physically connected state, overcoming the urging force of the spring 16 and causing the terminal rod 11 to be withdrawn downward together with the terminal cover 12. At this point, the limit switch 13 is not operating, and the terminal rod 11 is not supplied with electric power. When the terminal rod 11 and the terminal cover 12 are further retracted, the terminal cover 12 actuates the limit switch 13, and the power supply control circuit 14 for turning on / off the power supply to the terminal rod 11 is turned on, and the terminal rod is turned on. Power is supplied to 11. In this way, when the limit switch 13 is configured to detect the withdrawal of the terminal cover 12 that mechanically protects the terminal rod 11, as compared with the case where the limit switch 13 that separately detects the placement of the handy terminal 1 is provided. The number of parts is reduced, and the number of assembly work is also reduced.

Although the terminal rod 11 and the terminal cover 12 have a structure that can be independently retracted with respect to the bottom surface 10, the tip of the terminal rod 11 is slightly projected from the terminal cover 12, and It is also possible to have a structure in which the terminal cover 11 and the terminal cover 12 are integral with each other and can freely move out of the bottom surface 10.

Further, referring to FIG. 2, a device configuration other than the charging terminal 4 of the optical communication device 2 will be described. Reference numeral 1 is a handy terminal, 2 is an optical communication device, and 4 is a portion corresponding to a charging terminal. As shown in the figure, the optical communication device 2 is required for optical communication such as the mode changeover switch 34, the multi-connection circuit 35, the optical coupling interface 36, the first interface 37, the second interface 38, the changeover switch 39, and the communication monitor 40. It has a circuit. Reference numeral 30 is a power switch, 31 is a power supply, 32 is a power supply monitor display, and 33 is a charging monitor display. When the power switch 30 is turned on, 100V AC from the power source 31 is applied to the power control circuit 14, and the power monitor display 32 is lit.

When the mode changeover switch 34 is set to “charging only” 34a, the optical communication circuit does not operate, and the power supply control circuit 14 charges the battery 1c via the battery terminal 11a, and the power supply terminal 11b and the power supply 1d. Are not electrically connected. At this time, the charging monitor 33 lights up. When the mode changeover switch 34 is set to "communication only" 34c, the adapter power supply of the power supply control circuit 14 is electrically connected to the power supply 1d through the power supply terminal 11b, and the handy terminal 1 is driven by this power supply 1d. The charging terminal 11a and the battery c are not electrically connected and charging is not performed. At this time, the communication monitor 40 lights up. When the mode selector switch 34 is set to "charging and communication" 34b, the charging terminal 1a, the battery 1c, the power source terminal 11b, and the power source 1d are electrically connected. At this time, the charging monitor 33 and the communication monitor 40 are turned on.

The limit switch 13 is connected to the power supply control circuit 14 and the multi-connection circuit 35, and these circuits 14 and 35 operate when the limit switch 13 detects the exit of the terminal cover. Thus, the limit switch 13 serves not only as a switch for operating the charging terminal 4 but also as a switch for operating optical communication. The main function of the multi-connection circuit 35 is a level conversion function between the light from the optical coupling interface 36 and the RS232C of the first and second interfaces 38 and 37. The switching between the first and second interfaces 38, 37 and the like is performed by the master 39a, the slave 39b, and the independent 39c of the changeover switch 39.
