Abstract
A sheet electrical resistance measuring device includes: a housing having a gap for receiving a sheet therein; a sheet pulling member comprising a first and second rotating rollers that are disposed in the housing and pulls the sheet inserted into the gap; a stopper that is disposed in the housing and causes the sheet pulling member to stop pulling the sheet; and a pair of electrodes that is disposed in the housing and measures electrical resistance of the sheet which is stopped and brought into contact with the pair of electrodes. The sheet electrical resistance measuring is capable of reducing the likelihood of wrinkles to be occurred when inserting the sheet, thereby increasing measurement accuracy of the sheet electrical resistance measuring device.

A sheet electrical resistance measuring device comprising:
- a housing having a gap for receiving a sheet therein;
- a sheet pulling member that is disposed in the housing and pulls the sheet inserted into the gap;
- a stopper that is disposed in the housing and causes the sheet pulling member to stop pulling the sheet;
- and
- a pair of electrodes that is disposed in the housing and measures electrical resistance of the sheet which is stopped and brought into contact with the pair of electrodes,
- wherein the housing includes a first housing, a second housing, a joint section which connects end portions of the first housing and the second housing, and a sensor, apart from the pair of electrodes, is disposed on either the first housing or the second housing to detect a leading end of the sheet and to cause the sheet pulling member to stop pulling the sheet in response to having detected the leading end of the sheet so as to prevent the sheet from contacting the joint section, and
- wherein the gap is formed between the first housing, the second housing and the joint section so that the sheet is inserted into the gap in a flat manner along a pulling direction of the sheet pulling member.
