Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a terminal input/output device having a terminal data processing circuit connected to a central processing unit, and particularly to a portable input device having an input key and a device for use in the portable input device. The present invention relates to a terminal input/output device consisting of a main body device having a holder.

<Conventional technology> In order to perform product sales management, inventory management, etc. accurately and quickly, a data processing device is installed on the product transport vehicle along the sales route, and various data such as product number and quantity are input for each transaction location. However, an in-vehicle terminal input/output device that aggregates, edits, and processes data has been developed. This type of in-vehicle terminal input/output device is
A portable input device (handheld terminal; hereinafter referred to as HHT) having an input key and this HHT
It consists of a main unit equipped with an HHT holder having an opening for inserting the HHT, and a terminal data processing circuit is provided within this main unit.

<Problems to be solved by the invention> In conventional in-vehicle terminal input/output devices,
When the HHT is pulled out from the main unit, the inside is always exposed through the insertion opening of the HHT holder, allowing dust to enter.
It adheres to the connector between the HHT and the main unit, causing poor connections, poor insulation between terminals, and terminal deterioration, which is a problem especially when used in dusty areas such as sandy areas or industrial areas.

The purpose of the present invention is to provide a terminal input/output device that prevents dust from entering the HHT holder and improves the reliability of connector connection.

<Means for Solving the Problems> In order to achieve this object, the present invention provides a portable input device having an input key and a connector at the center of the bottom, a holder for accommodating the portable input device, and a holder for the portable input device. In a terminal input/output device consisting of a main unit having a connector connected to a connector, the mobile input device insertion opening of the holder is normally held in a closed state, and when the mobile input device is inserted, the mobile input device A lid to be pushed open is provided with its tip facing downward and tilted at an angle other than horizontally, and foreign matter on the lid is placed in contact with the holder portion with the tip when the lid is closed. It has a discharge part for discharging.

<Function> When the portable input device (HHT) is removed, the insertion opening of the HHT holder is always closed by the lid. Since the lid is sloped and a discharge part is provided in the holder part that is in contact with the tip of the lid, dust on the top surface of the lid falls from the discharge part to the outside of the holder along the slope of the lid, preventing HHT insertion. Do not enter the inside of the holder.

<Example> Figure 1 shows the HHT of the terminal input/output device according to the present invention.
FIG. 2 is a sectional view of the holder, and FIG. 2 is a perspective view thereof. This terminal input/output device includes an HHT 1 having an input key 13 and a main unit 18 having a built-in terminal data processing circuit. Configure. Main unit 1
8 and the printer unit 9 may be constructed as a separate assembly so that they can be replaced separately.
The HHT holder 2 is provided on the front side of the main device 18. The HHT insertion opening 2a at the top of the holder 2 is provided with a lid 3 that slopes downward toward the outside (front side) of the holder 2. The lid 3 is always urged in the closing direction (clockwise direction) by the spring 4. The tip of the lid 3 comes into contact with the upper edge of the front wall of the holder 2, so that the lid 3 is always kept closed. The bottom of the holder 2 is provided with a connector 6 for connecting to the connector 5 of the HHT 1. HHT insertion slot 2 of holder 2
Guide walls 7 of the HHT 1 are provided on both sides of the front upper part of the lid 3 of a. A gap 8 is formed in the lower part of the guide wall 7 so that dust on the upper surface of the lid 3 can fall.
When HHT1 is inserted into holder 2 as shown by arrow A, lid 3 is pushed open as shown by arrow B against spring 4, HHT1 is housed in holder 2, and HHT
1 connector 5 and the main unit side connector 6 are connected. As shown in FIG. 3, both side walls 10 of the holder 2 have stepped portions 1 so that the upper side of the lid 3 is thicker.
1, and when the lid 3 is closed, the lid 3 is formed into a stepped portion 11.
It is desirable that the lid 3 be brought into contact with both edges of the upper surface of the lid 3 to reliably prevent dust from entering.

The usage status of the terminal input/output device according to the present invention is shown in the fourth section.
The figures are shown in FIGS. FIG. 4 shows the device installed above the driver's side window of a truck for transporting goods. Figure 5 shows that at a business partner such as a supermarket, an operator actually checks the product and records data such as the product number and quantity on HHT1.

Each circuit is driven using a power supply voltage of 7. Also, when the HHT1 is installed in the main unit, the battery 37 is connected via this power supply control circuit 35.
is charged by the power supply voltage from the main unit. Data input from the keyboard unit 29 is sent to the processor 33 via the input/output control circuit 31, and the processor 33 aggregates and edits the data according to the control program in the ROM 34. The edited data is sent to the memory circuit 36 of the second printed circuit board 39 and stored therein. The data stored in the memory circuit 36 is read by the processor of the main unit when the HHT is installed in the main unit, edited as print data, and printed. Input data from the keyboard unit 29 is displayed on a liquid crystal display 30 via an input/output control circuit 31.

When the HHT 1 is removed from the in-vehicle terminal unit and installed in the CIU installed in the office, the data is sent to the modem 42 on the host computer side via the modem 41 as shown in FIG.
Data is input to the host computer 44 via 3. The line 45 connecting both modems may be a directly connected dedicated line or may be a public line.

<Effects of the invention> The HHT insertion slot of the HHT holder is equipped with a lid that can be pushed open and is always closed, so when the HHT is removed, dust does not enter the inside of the holder, and since the lid is slanted, the lid is closed. Dust does not adhere to the top surface, and since the holder part in contact with the tip of the lid is provided with a discharge part, the dust falls to the outside of the holder through the discharge part. Therefore, dust accumulated on the top surface of the lid will not be pushed into the interior by inserting the HHT. Therefore, when a connector for an electronic circuit that operates by a weak current, especially an optical connector, is installed in the holder, the reliability of the connection due to dustproofing is greatly improved.
