Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to portable information processing devices such as lamp-top personal computers and Japanese word processors, and particularly relates to the structure and handling of main bodies and printer devices. , regarding safety improvements.

[Conventional technology]

Portable information processing devices such as personal computers and Japanese 2-1 processors, which have become rapidly popular in recent years, are equipped with input devices such as keyboards inside the main body, as shown in Japanese Utility Model Application Publication No. 160526/1983. The control board, external storage device, power supply, etc. are arranged, and the display device is housed in the lid that can be opened and closed.

In such a configuration, when in use, the lid is opened, the display device is propped up, and input and editing operations are performed.

The printer device that serves as an output device after inputting and editing can be integrated into the main body, or it can be separated from the printer device to further improve the portability of the main body. be.

The former type has somewhat poor portability due to the weight and shape of the printer device, so the printer device is increasingly separated from the main body and connected with a cable when used.

[Problem to be solved by the invention]

The above-mentioned printer device detachable type has a disadvantage of poor operability, since the printer device cannot be removed from the main body unless the printer device is moved slightly while pushing the slide 1 to the knob with both hands. Ta. Conversely, when the main body and the printer device are connected, the connection cable between the printer device and the main body must be housed in the groove in the front surface of the printer case before the connection is performed, which poses a problem in terms of operability.

Furthermore, since the main body and the printer device are connected while being pressed, there is a problem in terms of operability in that it is difficult to tell whether or not they are completely locked.

In addition, the number of structural parts such as slide knobs and lock parts was large, and there was also a problem in terms of price.

One object of the present invention is to provide a structure that has a simple configuration, allows a printer device to be reliably connected to a printer device through simple operations, and also improves the storage properties of connection cables.

[Means to solve the problem]

In order to achieve the above object, the main structure of the present invention is that a locking mechanism is provided to connect the main body by placing the main body above the printer and pushing it downward. Specifically, the main body and the printer device are connected by a lock lever having a fitting protrusion and a fitting hole provided on the other side and fitting the two together.

Further, in order to prevent the lock lever from becoming unfitted, a spacer provided on the cover for preventing unfitting is brought into contact with a lock release button provided at the tip of the lock lever to maintain the coupled state.

To release the lock, rotate the cover and open it.
The structure allows for easy removal by simply lifting the main body upward while releasing the spacer from the lock release button and moving the lock button in the unfitting direction with both hands.

[Effect]

According to the above-mentioned means, the printer apparatus can be operated simply by engaging the guiding grooves formed on both sides of the printer lower case of the printer apparatus with the guiding protrusions formed on both sides of the printer lower case and pushing the main body downward. It is something that can be combined. The locking device for preventing detachment has a structure that can be automatically locked when the fitting protrusion of the lock lever engages with the fitting hole on the back surface of the main body while the main body is being pushed downward. Furthermore, since the cable storage section is integrally formed in the printer lower case, the connecting cable can be stored in the cable storage section at the joint section.

The cover covers the cable storage section and is rotated to open and close.

When the cover is closed, a spacer provided on the cover to prevent movement of the lock release button at the tip of the lock lever comes into contact with the cover to maintain the locked state.

When removing the main printer from the printer, open the cover, release the spacer from the lock release button, and then lift the main unit upward while pushing the lock release button at the tip of the lock lever formed on the lower printer case backwards with both hands. It can be disengaged with a chisel.
