Method of detecting home position, image reading device employing the method, and non-transitory computer readable recording medium therefor

A method of controlling an image reading device having an original platen supporting an original, a cover configured to be open and close relative to the original platen, a detector configured to detect whether the cover is opened or closed, a reader configured to read the original supported on the original platen, an operation part, includes:

• a receiving step of receiving selection information through the operation part, the selection information indicating a first function is selected or a second function is selected;
• when the receiving step receives the selection information indicating the first function, a reading step and a moving step repeatedly until receiving an input information indicating completion of image data of a plurality of originals read by the reader as one file, the moving step including moving the reader to a reading end position from a reading start position and moving the reader toward a waiting position opposite to the reading end position with respect to the reading start position from the reading end position;
• when the receiving step receives the selection information indicating the second function, the reading step and the moving step;
• and
• a determining step of determining whether the waiting position coincides with a regular position,
• wherein the determining step does not determine until receiving the input information when the receiving step receives the selection information indicated the first information,
• wherein the determining step does not determine in response to detection of opening of the cover by the detector before the reader reaches the waiting position when the receiving step receives the selection information indicating the second function, and
• wherein the determining step determines when opening of the cover is not detected by the detector before the reader reaches the waiting position.

A non-transitory computer readable recording medium for an image reading device having an original platen supporting an original, a cover configured to be open and close relative to the original platen, a detector configured to detect whether the cover is opened or closed, a reader configured to read the original supported on the original platen, an operation part, and a controller,

• wherein the recording medium contains instructions causing, when executed by the controller, the image reading device to execute:
• a receiving process of receiving selection information through the operation part, the selection information indicating a first function is selected or a second function is selected;
• when the receiving process receives the selection information indicating the first function, a reading process and a moving process repeatedly until receiving an input information indicating completion of image data of a plurality of originals read by the reader as one file, the moving process including moving the reader to a reading end position from a reading start position and moving the reader toward a waiting position opposite to the reading end position with respect to the reading start position from the reading end position;
• when the receiving process receives the selection information indicating the second function, the reading process and the moving process;
• and
• a determining process of determining whether the waiting position coincides with a regular position,
• wherein the determining process does not determine until receiving the input information when the receiving process receives the selection information indicated the first information,
• wherein the determining process does not determine in response to detection of opening of the cover by the detector before the reader reaches the waiting position when the receiving process receives the selection information indicating the second function, and
• wherein the determining process determines when opening of the cover is not detected by the detector before the reader reaches the waiting position.
