The present invention relates to a time recorder having a function to do.

[Conventional technology]

With the electronic time recorders currently in use, when you insert a time card into the card slot, the card feed roller installed on the guide passage rotates and draws the time card inside the recorder, and the print step is determined accordingly. At the same time, when the printing of various data by the printer is completed, the above-mentioned card feeding roller is reversed to automatically feed the time card back to the original insertion slot.

[Problems to be solved by the invention]

However, when a defective time card that is bent or curled is inserted into the time recorder having the above structure, there is a problem that the time card is caught inside the recorder and jams.

That is, the time card used for the time card automatic pull-in type time recorder as described above has a paper thickness of JI.
Since it is specified by S and is made thinner than general time cards that are manually inserted and removed, bending and curling are very likely to occur, and especially when the card is ejected, the upper end of the card is a corner of the guide passage. There were many problems such as being caught in the seams and clogging inside the guide passage.

Also, if such a card jam is left as it is, the next printer cannot use it, so it is necessary to take out the jammed time card immediately. ), Etc., cannot be taken out unless the case is removed, and the time recorder cannot be used during that time, which causes a problem in recording work data.

Therefore, the technical problem of the present invention is that if the time card is caught in the middle of the guide passage due to bending or curling and is jammed, the jammed time card can be removed without removing the case. The purpose is to automatically clear the card jam by ejecting automatically toward the exit.

[Means for solving problems]

Means taken in the present invention to solve the above technical problems will be described below with reference to the functional configuration diagram shown in FIG.

When the time card is inserted into the insertion port, the feed rollers 6 and 8 provided on the guide passage are rotated forward by the motor 7 to draw the inserted time card into the printing position, and the printer 11
When the printing by is completed, the motor 7 rotates the feed rollers 6 and 8 in the reverse direction to send the time card back to the insertion slot.
