[Prior art]

 Generally, a portable information processing device has a structure in which power is supplied to the main body by a removable power pack, so when removing the power pack, save the state immediately before that and then turn it on again. A resume function that reproduces the above conditions is required. Therefore, the conventional power pack attachment / detachment mechanism intentionally activates the resume function by sequentially operating the knob that operates the switch for the resume function and the lock release knob for removing the power pack one after another to carry the power pack. The structure is such that it is detached from the main body of the information processing device. The conventional technique will be described below in detail with reference to the drawings. FIG. 2 is a plan view of an embodiment of the prior art. 1'is a main body of a portable information processing device, 2'is a power pack which is slidable in the direction of an arrow and is attachable to and detachable from a main body 1 ', 2'a and 2'b are concave parts of the power pack 2', 3'is a tip. Is in contact with the concave portion 2'a and slides in the direction away from the concave portion 2'a, 3'a is the convex portion of the locking nail, 4'is a switch for resume function, 5'is a stopper, 7'is A power supply connection spring that comes into contact with the power supply pack 2'for electrical continuity, 8'is a power supply pack terminal, 9 is a lock release knob that slides in the direction of the arrow, 9a is a protrusion of the lock release knob 9, and 10 is an arrow mark. Switch operating knobs that slide in the direction 10a and 10b are convex portions of the switch operating knob 10, 6'is abutting against the lock 3 ', the lock release knob 9 and the switch operating knob 10, respectively, and a return for pushing back to the original position. It is a spring. In order to remove the power pack 2'from the main body 1'in the structure of FIG. 2, first, the switch operating knob 10 is slid in the direction of the arrow. As a result, the convex portion 10b turns on the switch 4 ', and then the convex portion 10a disengages from the lock release knob 9 to release the operation restriction of the lock release knob 9. Next, the lock release knob 9 is slid in the direction of the arrow without returning the switch operating knob 10 to the original position. At this time, since the convex portion 9a and the convex portion 3'a are in contact with each other, the lock pawl 3'also slides in conjunction with the lock release knob 9, and the lock pawl 3'is disengaged from the concave portion 2'a. The power pack 2'is unlocked, pushed out by the power connection spring 7 ', and slides and stops until the recess 5'b is caught by the stopper 5'. After that, pull out the power pack 2'by hand. Here, the lock claw 3'and the lock release knob 9 are separated from each other when the switch operating knob 10 is in a fixed position and the power pack 2'is mounted so that the lock claw 3'will not move to the power pack 2 '. It is necessary to automatically push in at the corner R, and if the lock claw 3'and the lock release knob 9 are integrated, the operation is restricted by the switch operating knob 10 and the lock claw 3'cannot escape. This is because. On the other hand, if the structure is such that the lock release knob 9 can freely move when the switch operation knob 10 is in the fixed position, the lock claw 3'and the lock release knob 9 can be integrated, but before the switch 4'turns on, the power pack 2 'Is removed and the resume function does not work. Therefore, the parts of and are also indispensable in this configuration. Conventionally, the power pack attachment / detachment mechanism has the above-described configuration.

[0003]

[Problems to be solved by the device]

 However, when the power pack 2'is removed, it is necessary to operate the switch operation knob 10 for the resume function and the lock release knob 9 of the power pack 2'each time, and the operation procedure is fixed, which is very troublesome. It was a thing. Further, the structure having the switch operating knob 10 and the lock releasing knob 9 becomes complicated, and there is a problem that the number of parts is large and the cost is high. The present invention solves the above problems, and it is possible to realize a structure with a very simple structure, in which the power supply pack can be attached to and detached from the device body while automatically performing the switch operation of the resume function with a simple operation. The purpose is to

[0004]

[Means for Solving the Problems]

 As a means for achieving the above object, the present invention releases the lock for preventing the power pack from coming off and operates the switch for the resume function by interlocking them with one knob, and the power contact for the unlocked power pack is used. By installing a stopper that pauses before leaving, and ensuring the avoidance time for operating the resume function, the power pack can automatically operate the resume function by a simple operation with a very simple structure. It is characterized by being more removable.

【Example】

 Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a plan view of an embodiment of the present invention. A power supply pack 2 is slidably mounted on the portable information processing device main body 1 in the direction of the arrow, and a lock 3 abuts on a recess 2a of the power supply pack 2 and stops without popping out. The lock 3 is arranged so as to be pushed by the return spring 6 from the opposite side of the power pack 2, and the convex portion 3a is set to turn on the switch 4 by sliding. The stopper 5 abuts on the concave portion 2b of the power pack 2 to temporarily stop the fall prevention when the power pack 2 is removed. The power supply connection spring 7 and the power supply pack terminal 8 are in pressure contact with each other to establish continuity. In the procedure for removing the power pack 2 in this structure, first, the lock 3 is slid in the direction of the arrow to push the switch 4 by the convex portion 3a to turn it on. However, at this time, the lock 3 is not disengaged from the recess 2a, and the power pack 2 is still in the locked state. When the lock 3 is further slid in the direction of the arrow, the lock 3 is disengaged from the recess 2a, and the power pack 2 is pushed by the power connection spring 7 and starts sliding. When the power pack 2 is slid a little, the stopper 5 is caught in the recess 2b and temporarily stopped. In this paused state, the power supply connection spring 7 and the power supply pack terminal 8 are still in contact with each other, and the power supply is supplied to the main body, so that the avoidance time for the resume function to work can be secured. After that, the power pack 2 is manually pulled out from the main body 1 and removed. Although the configurations of the present embodiment have been described above, the present invention is not limited to these configurations. For example, the lock 3 may have a shape integrated with the return spring 6, and the return spring 6 and the main body 1 may be formed. It may be integrated. Further, the lock 3, the return spring 6 and the main body 1 may all be integrated. Further, the stopper 5 and the main body 1 may be integrated, or conversely, the stopper 5 may be attached to the power pack 2 or integrated. Any material such as metal or resin can be used as long as it has spring properties. These will reduce the number of parts even further. Next, there is a high degree of freedom in the overall arrangement, and the lock 3 and stopper 5 may be placed anywhere, and there is no problem in integrating the two functions together. Furthermore, the lock 3 can be attached to or integrated with the power pack 2, and there is no problem. On the other hand, the power supply connection spring 7 for pushing out the power supply pack is not limited to these configurations, and a spring can be attached to the power supply pack 2 without any problem, and another spring is installed not on the power supply terminal but on the main body 1 or the power supply pack 2. Or it may be integrated. Further, in the present embodiment, the power pack 2 is attached and detached while sliding in a planar and linear manner. However, the present invention is not limited to this, and the power pack 2 can be attached and detached by rotation, movement in the sectional direction, insertion by one side hook, etc. without any problem. Inventive configurations are possible.
