Claim 2

Dependent Claim 130 words

A terminal input apparatus comprising a portable input device having a data input key and a main device provided with a holder for holding said portable input device therein, said holder having a main device side connector which is to be connected to a portable input device side connector arranged in the lower portion of said portable input device, wherein said holder is arranged so that said holder can be moved relative to said main device between a storing position at which said stored portable input device is parallel to said main device and an extraction position at which said portable input device insertion opening of said holder is projected toward an operation face of said main device and said portable input device is inclined relative to said main device.

Claim 3

Dependent Claim 45 words

A terminal input apparatus as set forth in claim 1, wherein a lid tilting downward toward the front is mounted on said insertion opening of the holder, and said lid is normally closed by a spring and can be pushed out downward against said spring.

Claim 4

Dependent Claim 42 words

A terminal input apparatus as set forth in claim 2, wherein both side plates of said holder have a thickness-increased portion above said lid and the bottoms of said thickness-increased portions of said side plates cover both side edges of said lid.

Claim 5

Dependent Claim 48 words

A terminal input apparatus as set forth in claim 1, wherein said connector comprises a non-contact type light connection portion and a mechanical contact type connection portion capable of being electrically connected with a connecting terminal in an insertion hole by insertion of a pin in said hole.

Claim 6

Dependent Claim 31 words

A terminal input apparatus as set forth in claim 4, wherein means for closing said pin insertion hole of said connector is arranged in an opening of said pin insertion hole.

Claim 7

Dependent Claim 78 words

A terminal input apparatus as set forth in claim 5, wherein said closing means comprises two closing members capable of elastically touching and separating from each other, said closing members being arranged in parallel to each other so that they are in contact with each other on the axis of said insertion hole, and said two closing members can be pushed outward to be separated from each other by insertion of said pin into said pin insertion hole.

Claim 8

Dependent Claim 58 words

A terminal input apparatus as set forth in claim 5, wherein said closing means comprises a thin plate of a conductor covering said insertion hole, and when said pin is inserted in said hole, said thin plate is pressed against and deformed by said pin to be in electrical contact with said connecting terminal in said insertion hole.

Claim 9

Dependent Claim 60 words

A terminal input apparatus as set forth in claim 4, wherein said pin impinges against a top end portion of said connecting terminal in said insertion hole to push said connecting terminal against a spring and press said pin against said top end portion of said connecting terminal, whereby electrical connection is accomplished between said pin and said connecting terminal.

Claim 10

Dependent Claim 39 words

A terminal input apparatus as set forth in claim 1, wherein said main device has a projection formed above said portable input device stored in said holder at said storing position to prevent dislodging of said portable input device.

Claim 11

Dependent Claim 29 words

A terminal input apparatus as set forth in claim 1, wherein a lock means disposed for securing and holding said holder in said main device at said storing position.

Claim 12

Dependent Claim 62 words

A terminal input apparatus as set forth in claim 1, wherein said portable input device includes a keyboard unit having a data input key, a processor for processing data, a memory circuit, a battery and display means, and said main device includes wiring means for connection to an external power source, a transformer, a control circuit having a processor, and a printer.

Claim 13

Dependent Claim 37 words

A terminal input apparatus as set forth in claim 11, wherein said main device is mounted on a truck and is connected to a truck battery through said wiring means for connection to an external power source.

Claim 14

Dependent Claim 133 words

A water-proof and dust-proof connector structure in which a first connector and a second connector are connected together to mechanically contact a first contact projected from said first connector with a second contact formed in the interior of an insertion hole of said second connector so as to electrically connect said first contact with said second contact, said connector structure being characterized in that two closing members capable of elastically touching and separating from each other are arranged in parallel to each other and disposed above said second contact in said insertion hole of the second connector so that said two closing members are in contact with each other on the axis of said insertion hole, and by inserting said first contact in said insertion hole, said two closing members are pushed outward.

Claim 15

Dependent Claim 133 words

A water-proof and dust-proof connector structure in which a first connector and a second connector are connected together to mechanically contact a first contact projected from said first connector with a second contact formed in the interior of an insertion hole of said second connector so as to electrically connect said first contact with said second contact, said connector structure being characterized in that two closing members capable of elastically touching and separating from each other are arranged in parallel to each other and disposed above said second contact in said insertion hole of the second connector so that said two closing members are in contact with each other on the axis of said insertion hole, and by inserting said first contact in said insertion hole, said two closing members are pushed outward.

Claim 16

Dependent Claim 45 words

A connector structure as set forth in claim 13, wherein each of said two closing members is cylindrical sleeve and both of said sleeves are gripped by a hair pin type spring for urging said sleeves so that they are in contact with each other.
